LED-based Edge Lighting Targets Automotive Apps

Tue, 05/10/2011 - 6:39am
edge lighting for autoLED-based edge-lit illumination from Global Lighting Technologies (GLT) offers an array of efficient solutions for automotive lighting from backlit dashboard displays to interior and exterior lighting. The company specializes in focusing the light emitted from white LEDs placed along one or more edges of a custom designed light guide and then extracting this light in a highly efficient and uniform manner. The light extraction technologies enable the bright, uniform light with the high efficiency – and lowest part count – possible. Applications include backlighting of automotive interior displays such as digital instrument clusters, infotainment systems, GPS displays, DVD players and other daylight-readable displays used in cars and minivans. GLT also creates custom light guides to illuminate HVAC controls, PRNDL shift indicators and door sills as well as dome lights, map lights, and accent lighting. Edge-lit light guides are also being used to illuminate manufacturers’ logos on the inside and outside of a car, as well as in an innovative braking light system that employs four light guides, one on each side of the car and two in the trunk lid, to illuminate the well when the lid is opened.
